Airspeed Calibration

[RV8Driver]

Is there a way to calibrate the airspeed on the SV? I have a backup analog airspeed and it shows about a 7 knot difference between the SV. They are both plumbed to the same pitot static source.

There isn't. We'll be adding a zero pressure calibration, but this is to nail the zero point, which is tough to do with accuracy over time, with the particular goal of to being able to do very low airspeeds well (sub 50 knots or so, say). At cruise, the pressures we're measuring are more substantial, and our calibrations have been found to be are pretty rock solid whenever we've had a unit back to check it out.

Maybe your analog unit is incorrect.

I found our Dynon Classic panels to be more accurate than the certified test equipment we used for pitot / static tests. The calibration chart for the equipment was such that we were giving more accurate raw data.
